KIOXIA Corporation has added an industry-first 245.76 TB (terabyte) model to its KIOXIA LC9 Series (hereinafter referred to as the LC9 Series), a high-capacity NVMe enterprise SSD being developed for generative AI. Compliant with the PCIe 5.0 interface and compatible with the 2.5-inch and new E3.L form factors, this high-capacity SSD meets the performance demands of generative AI.

Generative AI requires large-capacity, high-speed, and highly efficient storage to store training datasets for large-scale language models (LLMs) and vector databases that support Retrieval Augmented Generation (RAG), which helps improve the accuracy of generative AI’s answers and the scalability of the database.

The 245.76 TB high-capacity product being added to the LC9 Series lineup is achieved by stacking 32 2 Tb (terabit) 8th generation BiCS FLASH 3D flash memory QLC chips, which are currently being developed using Kioxia’s high-precision wafer processing technology, material design, and wire bonding technology, into a single 154 BGA compact package, resulting in an 8 TB flash memory product with the industry’s largest capacity .

The LC9 series is also well suited for data lakes where massive data ingestion and rapid processing are essential. Unlike HDDs, where performance is often a bottleneck and expensive GPUs are often underutilized, the LC9 series offers high-density storage with high capacity per watt in a compact footprint. And with capacities up to 245.76 TB, you can replace fewer power-hungry HDDs, resulting in better performance, lower overall power consumption, fewer drive slots in the host system, and reduced cooling costs. The result is improved total cost of ownership (TCO) through power efficiency, density, and thermal management.
